But that’s just it… if you do a search on " www.youtube.com" for “emimusic” you get 233,000 results, including over 8100 videos from the user “emimusic” as official uploads (eg. the official Iron Maiden channel), with a handful of search results being other videos that happen to contain “emi music” as part of the title (most of them seem to be playlists that include video(s) from the “emimusic” channel).
If you do the same search for “emimusic” on “m.youtube.com” (where mobile devices connect to) you get 5,130 results, with almost none of them being from the “emimusic” YouTube member/channel… the database for mobile devices is not the same as the database for computers and tv-connected devices.
Therefore, most of EMI’s uploads to YouTube do not show up in a search done by a mobile device. Almost none of the EMI-uploaded videos are available for playing from a mobile device.
The EMI uploads do show up in a search on a computer (and on the WDTV). It’s just that EMI has flagged most of them to not play on the WDTV (and other TV-connected devices).
So it seems like the “filtering”, with respect to the iPad, comes from what database is being searched, and has no bearing on what videos are also flagged to be blocked from TV-connected devices.
